    On this past weekend I rode up to Huntsville all via back roads with a route I created on Garmin BaseCamp. The trip up was perfect as I just let the Garmin lead me all the way there, it even took me through a 20km snowmobile trail which was unexpected but did take me right to my destination.

    On Monday I started back home and entered another route I had created a completely different way. To my disappointment, my Garmin gave an error message that read "Only 50 points can be used for follow road navigation". :shock: :?

    I tried the route with off road navigation, but the Garmin than only showed the intersections with no turn instructions. To make matters worse the route did not follow the roads, but were instead straight lines "As the crow flies" to each road turn or intersection from the last.

    I was always under the impression that you can list thousands of waypoints, although in the case of creating routes I guess they are the actual street intersections and turns.

    Can anyone tell me what I did wrong when planning this route? Did I use too many turns on this route?

    I think maybe Dual Sport Bob might have the answers to this.

    Thanks

    That's how your GPS is supposed to work. "Follow Roads" navigation can only have a max of 50 waypoints, but "Off Road / Direct" routes can have up to 250 waypoints (different makes/models have different limits). To answer your question - yes, you had too many turns/waypoints for "Follow Roads" but not for "Off Road" routing.

    The straight line routes are the way all GPS used to work until "Auto-routing" was introduced in the mid-90's. I started GPSing with these "direct" routes and find it just as easy to use as Follow Roads routing, if the waypoints are placed correctly (i.e. at turn off points) as once you are on the road you stay stay on it until the next waypoint.

    Sometimes you MUST use Direct Routing if there is no road on your GPS map where you want to ride.

    Many thanks for your help here Bob.

    I also checked Garmin's website for the error message and your absolutely right.

    I than opened BaseCamp up and checked the properties of my two routes. The route up to Huntsville was exactly 49 points which is the reason it functioned perfectly, but the route back down in another direction was 188 points.

    I've redone the route down cutting out many points and also split the route into two sections. Each section is now less than 50 points, so I'm assuming that this would resolve the issue. :)
